Abomination is one of Hulk's worst enemies. He was once a soldier who served Thunderbolt Ross's army, before he was turned into a gamma powered monster with superhuman strength, superhuman speed, nigh-limitless stamina, regenerative abilities seemingly invulnerability & potentially immortality.
Emil Blonsky became Abomination. through an experiment by Thunderbolt Ross acting under the orders of his superiors. After Hulk had defeated Abomination, the latter went on a rampage on a city, forcing a remorseful Thunderbolt Ross to have Abomination trapped in a stasis capsule which placed at the bottom of the ocean.
Some years later, Abomination escaped and infiltrated the Agents of S.M.A.S.H.'s base to get his revenge on Hulk and Thunderbolt Ross where he tranquilized Skaar, She-Hulk, and Devil Dinosaur and even defeated A-Bomb, using some special goggles that can detect A-Bomb's invisibility. Then Abomination activated a gamma bomb and even a rocket that he would use to get away.
During Hulk's fight with Abomination, Red Hulk placed the Gamma Bomb into the rocket. After Abomination knocks Hulk and Red Hulk from the rocket, he discovers too later that the gamma bomb he activated is on the rocket. Following the explosion in the sky, Red Hulk states to the Agents of S.M.A.S.H. that it was unlikely that Abomination perished in the explosion.
